four workers are hired to weed a field by hand. each is given a plot which is 10 x 7 ft in size. what is the total area of the field?

Answers

Answer 1
1) Area = a*b
= 10*7
= 70
2) Four workers with four 70ft plots
= 4*70
=280 ft

Answer 2

The total area of the field is 280 sq. ft.

What is unitary method?

"A process of finding the value of a single unit, and based on that value we can find the required value."

What is the area of the rectangle?

"[tex]A=l\times w[/tex], where l is the length and w is the width."

For given question,

We have been given the dimension of a plot which is 10 x 7 ft

From the dimension we can say that, a plot must be rectangular in shape.

Here, length (l) = 10 ft

and width = 7 ft

Using the formula for the area of the rectangle,

[tex]\Rightarrow A=l\times w\\\Rightarrow A=10\times 7\\\Rightarrow A=70~ft^2[/tex]

This means, the area of each plot is 70 sq. ft.

Four workers are hired to weed a field by hand.

Using unitary method the total area of the field would be,

[tex]70\times 4= 280~sq.ft.[/tex]

Therefore, the total area of the field is 280 sq. ft.

By how much peter is overweight he is 105 kg his aim is to lose 500 g per week if he manages this how many weeks will it be until he is 90 kg

Answers

Hello There!

105 - 90 = 15kg
500g = 1/2 kg
Peter is 15kg overweight.
15 x 2 = 30
It will take him 30 weeks for this.

Hope This Helps You!
Good Luck :)
First I would turn 500g into kg and then set up an equation like the following.

So lets convert 500g to kg. We do this by using a conversion factor.
 [tex]1g = 0.001kg = 1g:0.001kg = \frac{0.001kg}{1g}[/tex]


Now that we know this conversion factor lets set it up.

[tex]500g \times \frac{0.001kg}{1g} = 0.5kg = \frac{1}{2}kg [/tex]

Ok now we know Peter wants to lose 0.5 kg or [tex]\frac{1}{2}kg[/tex] a week.



Peter wants to lose 1/2 kg a week so we use x for weeks

Lost of weight per week 
[tex] \frac{1}{2}x [/tex]

Next, it tells us that Peter wants to be 90 kg. So he needs to lose 15kg. 
105 - 90 = 15kg

Now we need to find out how many weeks will it be untill he is 15kg. So, Lost of weight per week = 15kg

[tex] \frac{1}{2}x = 15 [/tex]
Now solve for x in [tex] \frac{1}{2}x = 15 [/tex]

[tex] \frac{1}{2}x = 15 [/tex]
[tex] 2 \times \frac{1}{2}x = 15 \times 2[/tex]
[tex] x = 30 [/tex]
So it will take 30 weeks at 1/2kg a week to lose 15kg


Item 2 Solve the equation. 6.7x=5.2x+12.3

Answers

To solve for x, subtract 5.2x on both sides to get 1.5x=12.3. divide 1.5 on both sides to get x = [tex] \frac{123}{15}[/tex] or x = [tex] \frac{41}{5}[/tex] = 8.2

Jim had 3,067.48 in his checking account.He wrote a check to pay for two airplane tickets. His account now has 1,845.24. How much did each ticket cost

Answers

Each ticket is 244.648 because you subtract the money you had in the account from how much you had left. Then you multiply 1,223.24 by 2 because it says that Jim bought 2 tickets and that should get you 244.648.

Answer:

Cost of one ticket=611.12

Step-by-step explanation:

In this question we have given

Amount in account= 3067.48

After purchesing 2 airplane tickets, amount in Jim's account=1845.24

Therefore,

Cost of two tickets=[tex]3067.48-1845.24[/tex]

Cost of two tickets=1222.24

Therefore,

Cost of one ticket=[tex]\frac{1222.24}{2}[/tex]

Cost of one ticket=611.12

Answer :- Angle addition postulate is the reason which should appear in the box labeled 1.


Explanation:-

Angle addition postulate states that for a given angle ∠AOC if P is interior of ∠AOC then ∠AOC=∠AOP+∠POC.

In the given figure it can be seen that

C is interior of ∠BAD then by angle addition postulate

∠BAC+∠CAD=∠BAD which in box 1.

As a regular pentagon is dilated by a scale factor of 3 to create a new pentagon. Which statement is true?

F. The perimeter of the new pentagon is 9/4 the perimeter of the original.

G. The perimeter of the new pentagon is 9/2 the perimeter of the original.

H. The perimeter of the new pentagon is 15/2 the perimeter of the original.

J. The perimeter of the new pentagon is 3/2 the perimeter of the original.

Answers

Final answer:

When a shape is dilated by a scale factor, all lengths within the shape are multiplied by that factor. So, when the regular pentagon is dilated by a scale factor of 3, the perimeter of the new pentagon is 3 times the original. The correct answer is that the perimeter of the new pentagon is 9/2 the perimeter of the original.

Explanation:

In the subject of Mathematics, particularly with shapes and scaling, when a shape is dilated by a scale factor, all lengths within the shape are multiplied by that factor. So, when your regular pentagon is dilated by a scale factor of 3, this means that each side of the pentagon is multiplied by 3. As the pentagon has 5 sides, the total perimeter will be multiplied by 3 as well.

Therefore, the perimeter of the new pentagon is 3 times the perimeter of the original pentagon. This eliminates options F, H, and J, and we find that the correct answer is:

G. The perimeter of the new pentagon is 9/2 the perimeter of the original.

Answer:

The required inequity is: [tex]5x\leq 12[/tex]

The price of a gold fish should be less than or equal to $2.4 so that you can by 5 fish.

Step-by-step explanation:

Consider the provided information.

You have $12 to buy five goldfish for your new fish tank.

Let the cost of a goldfish is $x.

For 5 gold fish you needs to pay $5x.

Thus, the required inequity is:

[tex]5x\leq 12[/tex]

We use less than equal to sign as you can pay $12 but not more than it.

Now simplify the above inequity as shown:

Divide both the sides by 5

[tex]\frac{5x}{5}\leq \frac{12}{5}[/tex]

[tex]x\leq 2.4[/tex]

Thus, the price of a gold fish should be less than or equal to $2.4 so that you can by 5 fish.

Answers

This is asking which one has the most factors. Lets list them out:

75: 1,3,5,15,25,75
60: 1,2,3,4,5,6,10,12,15,20,30,60

Obviously 60 has more factors.

The answer is 60

Hope this helps!
Final answer:

Rectangular arrangements are made when the number of items can be arranged into rows and columns to form a rectangle. When comparing the number of these arrangements that can be made with 75 cookies and 60 cupcakes, the table with 60 cupcakes allows for more arrangements.

Explanation:

The subject of this question falls under the topic of mathematics, specifically, it is related to the concept of rectangular arrangements or factoring numbers. In this scenario, we have to determine which number (75 cookies or 60 cupcakes), when all items in a table are displayed, allows for more rectangular arrangements.

A rectangular arrangement can be made when the number of items can be arranged into rows and columns to form a rectangle. For instance, 12 items can form a 3x4 or 2x6 rectangular arrangement.

Now let's figure out how many rectangular arrangements can be made for each table:

75 (cookies) = 1x75, 3x25, 5x15 are three rectangular arrangements.60 (cupcakes) = 1x60, 2x30, 3x20, 4x15, 5x12, 6x10 are six rectangular arrangements.

So, the table with 60 cupcakes allows for more rectangular arrangements than the one with 75 cookies.
